Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
A low friction bearing arrangement for a ski boot in contact with a ski comprising: a. a slot located substantially transversely across the lower face of the sole of the ski boot, said slot having a smooth bottom surface and two lateral edges, and b. an anti-friction plate secured to the ski, said plate having an upper face and being engaged with said slot, wherein said bottom surface of said slot bears on said upper face of said anti-friction plate whereby the whole lower face of the sole is spaced from the ski and is freed from contact with the ski.
